Rubbing salt in the wounds! Man Utd legend Roy Keane reveals Sir Alex Ferguson's bizarre error amid the ex-captain's acrimonious exit from Old Trafford

Keane left Old Trafford in 2005 after an explosive interview with MUTV where he lambasted his team-mates was intercepted before it made it to the airwaves. Keane's contract was was cancelled by mutual consent, something that the Ireland international could understand, but the nature of the final meeting with manager Ferguson and chief executive David Gill still irks Keane nearly two decades on.

Recalling the end to his time at Old Trafford on The Overlap's Stick to Football podcast from Sky Bet, Keane said: "I got called into a meeting with Ferguson and Gill and before I sat down they say: 'Here we go, we've already prepared a statement, would you like to read it?' And they had the years wrong!"

Keane went on to reveal that that statement said he had been at the club for 11 and a half years when he had in fact served for a year longer.

Keane's departure from United and his clash with Ferguson remains an extraordinary chapter in the club's history. The feud between the pair remains with the Irishman adamant he will never speak to his former manager.

After leaving United, Keane moved north of the border to play for Celtic, winning a Scottish Premier League title before a knee injury forced him to retire at the age of 34.
